Question

Someone please explain the steps! Question from complex number..

Answer 1

Answer:

Here given that z1 * z1⁻ = 1  => z1⁻ = 1/z1  ----(i)

Similarly, z2 * z2⁻ = 1  => z2⁻ = 1/z2. ----(ii)

Now in the eqn., |1/z1 + 1/z2| = 3/2, we insert (i) and (ii), to get

|z1⁻ + z2⁻| = 3/2.........

And then the equation proceeds.........

Note:- z⁻ represents z bar.
